LANGRY Penetration Concrete Strength Tester SJY-1000B is suitable for masonry concrete strength tests. The penetration method is based on the correlation between the penetration depth of the nail into the concrete and the compressive strength of the concrete, using the lever force method, compressing the working spring to load, storing potential energy, and instantaneously penetrating the measuring nail into the concrete. A field detection method that converts the intensity by combining the penetration depth with the relevant intensity measurement curve.

• Simplifies operation and improves efficiency with instant energy release.
• Provides precise strength readings using standardized curves.
• Quickly and conveniently assesses strength without damaging components.
• Widely used in construction and engineering testing.
• The body adopts a lightweight design concept, making it more portable and easier to use.
• The clip uses a six-petal design for multi-angle clamping, making it more convenient to install the test nail.
• The innovative lever force application design simplifies the operation steps and improves work efficiency.
• High-strength test nails and nail gauges are included, made from high-strength materials, making the test nails more durable.
